For a casual outfit, try teaming a harrington jacket with a white crew-neck t-shirt — these pieces play perfectly well together. Complement your outfit with a pair of athletic shoes to make a mostly classic outfit feel suddenly fresh. Can you see how super easy it is to look stylish and stay cozy when chillier weather arrives, all thanks to combinations like this? Perfect to convey that even as a younger man you're confident enough to hold your own in the fashion department.
